' p This invention relates to; attachments for typesetting machinesandparticularly to a device especially designed". to be used on standardlinotypes; the principal Object of my invention being to provide adevice which will keep the reading faces of the matrices useddinfsuchmachines in a continuously clean and legible condition, and without anyattention on the part of the operator being a necessary other thananoccasional adjustment of the cleaningelement.' n j a p Another objectis to provide a device for a the purpose which may be attached to themachine in but a few seconds time, and Withoutmaking' changes of anycharacter to the machine.

A further object to construct device in'such a manner that Whilethe-"cleaning '1 A-further 'ea; of as invention *is to produce a; simpleand inexpensive device and yet :one which will .be exceedingly effectivefor the purpose for which it is designed. 7 These objects. lfaccomplishby -means of such structure and relative arrangement of parts as willfully appear by afperusal of the following specification and claims. j
